Abstract: A radiation imaging device (10). The radiation image device (10) comprises a subject radiation station (12) producing photon emissions (14), and at least one semiconductor crystal detector (16) arranged in an edge-on orientation with respect to the emitted photons (14) to directly receive the emitted photons (14) and produce a signal. The semiconductor crystal detector (16) comprises at least one anode and at least one cathode that produces the signal in response to the emitted photons (14).

Abstract: A website for marketing real estate or products relating to real estate includes personal webspaces for users. Assigned user roles determine which capabilities they may configure into their webspaces. Users may communicate with each other and with merchants, e.g., by sharing webspaces or by dialogs. Merchants may send product information only certain users in response to users' expressed or inferred desires. Collected product and user data may be used to calculate propensities of individual users, marketability of individual products, or market trends.
